The material is copper alloy,beryllium copper or aluminum bronze.Due to the good thermal conductivity of copper and high-quality stainless steel and the characteristics of almost no carbon, the heat generated in a short time is absorbed and conducted when the product is rubbed or impacted by an object.Another reason is that because copper and stainless steel are relatively soft, they have good concessions during friction and impact, and it is not easy to produce tiny metal particles.So we can hardly see the spark, the products achieve the explosion-proof effect.
The material of non sparking tools: Al-Br(QAl11-4-4), Be-Cu(QBe2)
Be-Cu: the color is green lake,hardness is not less than HRC35,tensile strength δ b 105-120kgf/mm2;standard code GBEX ⅡC,suitable for hydrogen with concentration 21.0±2.0%.Beryllium copper alloy with anti-magnetic performance.
Al-Cu: the color is bluish yellow,hardness is not less than HRC25,tensile strength δ b 75-85/mm2;standard code GBEX ⅡB,suitable for ethylene with concentration 7.8±0.5%,GBEX ⅡA (propane 6.5±0.5%),Ⅰ（methane 6.5±0.5%）。
Non sparking tools of XIN DA are made of high strength copper alloy.This kind hand tools can effectively prevent burning and explosion accidents caused by friction and collision between tools and tools in the flammable and explosive workplace.The explosion-proof performance received the certificates according to the national standard GB10686-2003, with the function of high intensity and good toughness.
The products are widely used in petroleum,chemical industry,mining,gas,coal,oxygen-producing,pharmacy,smelting,powder,leather,airplane,marine engineering etc,suitable for warehouse that operate flammable and explosive products,electrolytic workshops,communication assembly workshops,and requires that the tools are not rusty,wear-resistant and anti-magnetic during the checking process.
